UART connection on ADuCM350EBZ without internal loop

Question asked by canales47 on Mar 8, 2018

In the UartTest.c  explain how set an UART connection but it is with internal loop. I configure the pinMux with 3.7 and 3.6 pins and I see nothing on the osciloscope. How can I configure an UART external connection with this pins?

 

Another question. How the internal loop works? Because I remove the LK5 and LK3 jumpers of the USB-SWD/UART-EMUZ and the UartTest said me PASS even when I configure incorrect pins.

 

Best regards
